Terms of Service

This is a translation; if it differs from the Korean original, the Korean version prevails unless mandatory law says otherwise.

Effective October 23, 2026

These Terms set the conditions for using the app Cat's Study (the “App”) provided by Lo-Fi Labs Inc. (“we”). By using the App, you agree to them.

1. The service

The App offers a focus timer, records and stats, task planning, room and cat decoration, background sounds and a friends and crews feature, and needs an internet connection. The basic features are free; buying coins and the Pro subscription are paid (section 3A). The App has no boards, posts, comments, chat, messages or photo uploads. We may change or pause features when needed and will announce important changes in advance.

2. Eligibility and accounts

The App may be used by people aged 13 or older, or older if the law of your country of residence requires a higher age (in Korea, 14 or older). If you are a minor under the law of your country of residence, you need the consent of your parent or legal guardian, and when a minor uses the App, the parent or legal guardian is deemed to have agreed to these Terms.

Starting without signing in creates an anonymous account; if you delete the App or change devices, its records can't be recovered. To keep them, link a Google, Apple or Kakao account. Don't use anyone else's account.

3. Coins and items

Coins are earned through check-in, focus and streak rewards and rewarded ads you choose to watch, bought in the App, or received with a Pro payment (section 3A). Purchased and earned coins share one wallet, with no spending order or expiry. Coins and items are licenses for use inside the App with no cash value; they can't be exchanged for money or transferred to anyone else. Refunds for purchased coins follow section 3A. How they're earned is shown in the App and may change. We may take back coins or items obtained improperly, and any remaining coins and items are lost when you delete your account.

3A. Payments, subscriptions and refunds

• Where you pay: Coin purchases and the Pro subscription are paid through the store you got the App from (App Store or Google Play). We never receive payment details such as card numbers.
• Pro subscription: Monthly and yearly subscriptions and a one-time lifetime purchase are available. A subscription renews automatically at the then-current price and is charged to your store account unless you cancel at least 24 hours before the period ends. You manage and cancel it in your store account settings, not in the App. A free trial becomes paid on the day it ends unless you cancel before then. Prices, benefits and trial terms are as shown on the purchase screen; if a subscription price changes, the store will notify you and ask for your consent where required. Pro-only items can be used only while you have Pro and are taken off when Pro ends.
• Refunds: Refunds are handled by the store under its own policies. Users in Korea may withdraw a purchase within 7 days of buying it under the Act on the Consumer Protection in Electronic Commerce (this may be limited where the law allows, such as for digital content already used, and if so this is shown on the purchase screen), through the store's refund process. A purchase a minor made without a parent's or legal guardian's consent may be cancelled by the minor or the guardian. If you need help, contact support@catsstudy.com.
• Coins taken back after a refund: If the store refunds a purchase, we take back the coins that purchase gave you. They come out of your balance, including coins you earned, but your balance never goes below 0. Items you already bought stay with you. If a subscription or lifetime purchase is refunded, Pro ends too.
• If your account changes: If purchases from the same store account move to another App account (for example, restoring purchases after reinstalling the App), Pro moves with them, along with whatever coins from that store account's payments are left on the old account.

4. Ads

The App shows banner ads, rewarded ads and occasional full-screen ads when you finish a focus session; with Pro, no ads are shown. You watch rewarded ads only when you want to; rewards are granted when you watch to the end and it's recorded, with a daily limit. Advertisers are responsible for their ads.

5. Friends and crews

The friends and crews feature is available to users who have linked an account and agreed to the rules below when first turning it on. You become friends when you send a request by ID and the other person accepts. A crew is a small group you join with an invite code or a friend's invite (up to 3 crews per person, 12 people per crew). Others see only the fixed information in section 2 of the Privacy Policy and pats; there is no chat or free-form messaging. The crew owner who created a crew can rename it, remove members (removed people can't rejoin) or delete the crew.

• We have zero tolerance for objectionable content and for harassing other users. Users who break these rules may have their use restricted or their account deleted (section 6).
• Names, IDs and crew names may not contain contact details (phone numbers, messenger IDs, email, etc.), links or promotion, impersonation of other people or companies, or insults, hate or sexual content.
• You can report a name or crew name. If 3 different users report it within 30 days, the name is hidden automatically, and if it's a person, their friend requests, crew creation and invites are paused. After reviewing, we may unhide the name, change it or restrict use.
• Searching, requests, invites and pats have limits to prevent spamming.
• You can remove or block a friend at any time, and leave a crew at any time. Report objectionable names or behavior in the App or at support@catsstudy.com.

6. Prohibited conduct

• Getting records or coins by modifying the App, automation, or manipulating the device clock or server requests
• Fraudulent ad views or taps, attacking the servers, or reverse engineering or copying the App
• Harassing others, spamming or promoting through the friends and crews feature
• Copying or distributing the App's artwork, text or sounds without permission, or otherwise breaking the law

If you break these rules, we may take back coins or items, change your name, restrict your use of the friends and crews feature, or delete your account. You can object by email.

7. Deleting your account

You can delete your account any time with [Delete account] at the bottom of the Account tab; your account, records, coins and items are deleted immediately and can't be restored. Deleting your account doesn't cancel a paid subscription, so please cancel it in the store. If you can't use the App, ask us by email.

8. Rights

Rights to the App's artwork, characters, text, sounds and software belong to us or their rightful owners. Tasks, resolutions, names, crew names and other text you write belong to you, and we use them only to provide the service and to operate these Terms.

9. Limitation of liability

The service is provided as is. We aren't liable for causes beyond our control, such as disasters, network failures or device settings (notifications off, power saving, clock changes), or for records lost by deleting the App on an anonymous account. This doesn't apply to damage caused by our intent or gross negligence.

10. Changes and governing law

When we change these Terms, we'll announce it in the app or on this page with the effective date; if you disagree, you can delete your account. We'll give 30 days' notice before ending the service. These Terms are governed by the laws of the Republic of Korea, and disputes go to the competent court under the Korean Civil Procedure Act. Consumers abroad keep the rights given by the mandatory laws of their country.

Addendum: these Terms take effect on October 23, 2026.
